8.6 PLC configuration
The PLC configuration is an object on tab Resources in the Object Organizer and combines the
resources of the automation system.
The dialog box PLC Configuration describes the selected automation system for the project.
The resources of the automation system are described by the applied system organization units. The
available system organization units are dependent on the selected automation system.
•
The editor displays the configuration as a tree structure that can be edited via menu
commands and dialogs.
•
In the PLC configuration, the system organization units are attached to the automation
system as subordinate elements.
•
The editor displays inputs and outputs with an IEC address for input and output access. In
standard cases, a symbolic name may be assigned for each input and output for
identification, that will then be placed in front of the IEC address.
•
Any projects opened that were generated with an older DDS version and containing a PLC
configuration, can be transferred into the new Uniform Control Configuration format.

•
It is important for program generation to insert the required system organization units of the
selected Lenze automation system.
System organization units
System organization units are interfaces/organization units permanently integrated into the device
(quasi hardware interfaces) that cannot be programmed using the DDS (e. g. MCTRL_MotorControl,
DIGITAL_IO, DCTRL_DriveControl, AIF_IO, ANALOG1_IO, ...)
•
The DDS checks on the basis of the relevant system organization unit description whether the
IEC addresses applied in the program do indeed exist in the automation system.
The system organization units in the PLC configuration consist of several elements that are either
inputs or outputs.
•
Every input/output has a symbolic name (identifier) that can be changed if necessary and is
assigned an IEC address. Thus every input/output can be addressed directly (e. g. % IX1.0.1)
or via system variables (DIGIN_bIn1_b) in the program.
